The main objective of Ocean Thermal Energy Conversion (OTEC) is to turn the solar energy trapped by the ocean into usable energy. There is a main two types: Cloased cycle, and open cycle. Both can be built on land, and offshore platforms. The current system is a closed cycle type which operates the NH3 working fluid. The fluid is evaporated using warm surface seawater temperature. After the vapor drives the turbine, it is condensed by cold seawater temperature. This condensate is pumped back to the evaporator again. The system is  built based on design technique of modeling. Reverse Osmosis (RO) configurations are attached to the OTEC power plant. The load on the RO high pressure pump is considered a known input parameter to OTEC system. User should specify the productivity and some operating conditions for RO-energy recovery unit. User can select between different systems combined with RO. RO types are:
1. RO-Basic
2. RO-PWT
3. RO-PEX
The whole system contains the following:
1-Evaporator unit.
2-Turbine.
3-Condenser.
4-Pump.
5-Sea depth calculation.
6-RO with energy recovery units.
NH3 and seawater prop's are provided in excel sheets and embedded correlations.

**MatLab-SimuLink should be used to run the model.
